Definitions
- the MAC layer circuitry 108 may receive the interference samples from the physical layer circuitry.
- the interference samples 212 may be I/Q samples provided by RF/ADC circuitry 202 ( FIG. 2 ).
- Operation 414 may include repeating operations 402 - 412 periodically so that the transmit-active noise-cancellation matrix and the transmit-inactive noise-cancellation matrix can be updated as conditions change.
- the physical layer circuitry 110 may be selected either a transmit-active noise-cancellation matrix or a transmit-inactive noise-cancellation matrix depending on the state of the transmit-active signal 123 ( FIG. 1 ).
